Abstract
In some implementations, the disclosed technology determines that a microphone is likely closer to a sound source compared to other microphones partially based on determining a spectral standard deviation associated with an audio signal captured by the microphone. In some implementations, the disclosed technology determines a spectral standard deviation of audio signals associated with different microphones and determines that the microphone with the lowest spectral standard deviation is likely the closest microphone to a sound source. The disclosed technology can determine the closest microphone generally independent of input signal level, independent of microphone sensitivity, independent of microphone design, independent of microphone manufacturer, and independent of the sound source intensity (e.g., 'loud' or 'soft').
